Android时间选择器和日期选择器的用法

public class MainActivity extends Activity {

private TimePicker timePicker;
private DatePicker datePicker;
private Calendar cal;
private int year;
private int month;
private int day;
private int hour;
private int minute;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//获取日历的一个对象
cal = Calendar.getInstance();
year = cal.get(Calendar.YEAR);
//注意month是从0开始的
month = cal.get(Calendar.MONTH)+1;
day = cal.get(Calendar.DAY_OF_MONTH);
hour = cal.get(Calendar.HOUR_OF_DAY);
minute = cal.get(Calendar.MINUTE);
setTitle(year+"-"+month+"-"+day+"-"+hour+"-"+":"+minute);
timePicker = (TimePicker)findViewById(R.id.timePicker1);
datePicker = (DatePicker)findViewById(R.id.datePicker1);

//dataPicker初始化
datePicker.init(year, month-1, day, new OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
setTitle(year+"-"+(monthOfYear+1)+"-"+dayOfMonth);
}
});
timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
setTitle(hourOfDay+":"+minute);
}
});
//DataPickerDialog 日期选择对话框
/* new DatePickerDialog(this, new OnDateSetListener() {

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
setTitle(year+"-"+(monthOfYear+1)+"-"+dayOfMonth);
}
}, year, cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH)).show();*/
//TimePicker 时间选择对话框

}, hour, minute, true).show();
